Pic from manual and further info on torque settings.
Just doen this on a new head 4 days ago. Stuck STRICTLY to the manual and it runs sweetly. No tappet rattle.
As timmyt said, clearances (COLD) are:
Inlet 0.1mm +/- 0.05 (in old money 0.004" +/- 0.002")
Exhaust 0.2mm +/- 0.05 (in old money 0.008" +/- 0.002")
Rotate crankshaft clockwise until No.1 cylinder is at TDC with all rockers on No.1 cylinder loose.
Adjust the tappets marked '1' in the diagram. Some are inlet and some are exhaust so be careful you pick the right ones.
When correct setting, tighten locknut (torque setting 16-20Nm - or 11.8 - 14.75 ft lb). Check clearance again with feeler gauges.
Turn the crankshaft one revolution (360 degrees)and No.4 cylinder is at TDC with all rockers on No.4 cylinder loose
Adjust the tappets marked '4' in the diagram. Again, some are inlet and some are exhaust so be careful you pick the right ones.
When correct setting, tighten locknut (torque setting 16-20Nm - or 11.8 - 14.75 ft lb). Check clearance again with feeler gauges.
